Title	Minor Waste Pond Leakage at Cogema Mining
Event Description	The licensee reported the discovery of minor leaks detected in two of four surface evaporator waste ponds used as a portion of an uranium milling process. Each pond has a leak detection system which is checked once per week. The minor leaks were detected on 4/28/04 indicating some minor leakage through the pool liner. The licensee stated there was no release of liquid to the environment. Corrective actions planned are to pump down the two ponds and inspect and repair the liner as needed. This report was made pursuant to License Condition 11.4 which specifies to notify the NRC of any spills or leaks. The licensee also notified the Wyoming Department of Environmental Quality.
